George Michael's funeral has been delayed again as the coroner is still awaiting the results of toxicology tests

According to the Daily Star, important tests are still being carried out to determine the singer's cause of death and and he cannot be laid to rest until an inquest is opened.

On December 30, a post-mortem came back as "inconclusive" and Thames Valley Police revealed further examinations would be carried out on the late star but insisted his death was still being treated as "unexplained but not suspicious".

In a statement, they said of the post-mortem, which was carried out on December 29: "The cause of death is inconclusive and further tests will now be carried out.

"The results of these tests are unlikely to be known for several weeks. Thames Valley police will prepare a file for the Oxfordshire coroner.

"Mr Michael's death is still being treated as unexplained but not suspicious."

George's cousin said he thinks the singer was taking "hard drugs" before his death

Andros said George had been addicted to crack cocaine in the past, claiming it was one of his "favourite drugs".

He said: "I believe he had suicidal thoughts, because his mental health was all over the place. But I don't believe this was suicide."

It was claimed that George's boyfriend Fadi Fawaz - who dated the singer from 2012 until his death - had been interviewed by police on two occasions since his passing.

Previous reports stated that a major crime unit from Thames Valley, who specialise in murders and rapes, had been brought in to rifle through the file as they attempt to piece together the days leading up to the point George was found dead by his partner at his home.

A source told The Sun: "The investigation is now picking up a bit of speed.

"Officers from the Major Crime Unit have begun asking questions of those who were in the area at the time George died and the day before.

"They want to build up an idea of what George's last seven days were like and who came and went."

George Michael fans start cheeky petition to set up memorial bench at his favourite 'sex haunt'

The star famously joked about his sex life, and going cruising for men in the park

The scene begins with Gervais – as Andy Millman – strolling through Hampstead Heath after an audition. He comes across "the waiting bench" and soon finds out it’s a spot for gay men to find sexual partners.

George Michael appears as himself, asking if there’s “any action” at the bench, before revealing he’s on his lunch break from community service. When Gervais asks him what he did, Michael reveals it was for fly-tipping Annie Lennox’s fridge-freezer.

When asked how he got caught by the police, Michael says "Sting called the f***ing council because he’s a f***ing do-gooder." As he leaves the bench to check out another area of the park, he asks Gervais to "keep an eye out for paparazzi".
